64441871 ÷ 813 
Let's see how many times 813 fits into 64441871.

Moving on to step 1:
6 divided by 813 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 813

Let's proceed to step 2:
64 divided by 813 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 813

On to step 3:
644 divided by 813 is 0 with a remainder of 644.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 644 after subtracting 0 from 644.
Bring next digit (4) of the dividend behind the 644 and repeat the process: 6444 / 813

Advancing to step 4:
When dividing 6444 by 813, we get 7 with a remainder of 753.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 5691 from 6444 leaves us with 753.
Include the next digit (1) from the dividend after 753, then repeat: 7531 / 813

Let's proceed to step 5:
When dividing 7531 by 813, we get 9 with a remainder of 214.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 7317 from 7531, we get 214.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 813

Let's proceed to step 6:
813 can be fit into 2148 2 times, resulting in a remainder of 522.
The next digit of our result is 2. 
Result so far: 792.0
The remainder is 522 after subtracting 1626 from 2148.
Fetch the next digit (7) from the dividend, attach it to 522 and continue: 5227 / 813

Let's proceed to step 7:
5227 divided by 813 is 6 with a remainder of 349.
The number 6 becomes the next digit in our result. 
Result so far: 7926.0
If we subtract 4878 from 5227, we get 349.
Fetch the next digit (1) from the dividend, attach it to 349 and continue: 3491 / 813

Advancing to step 8:
When dividing 3491 by 813, we get 4 with a remainder of 239.
Use 4 as the next digit of our solution. 
Result so far: 79264.0
Deduct 3252 from 3491 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
2390 divided by 813 is 2 with a remainder of 764.
Record the quotient 2 as the next digit in the result. 
Result so far: 79264.2
The remainder is 764 after subtracting 1626 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Step 10:
7640 divided by 813 is 9 with a remainder of 323.
Record the quotient 9 as the next digit in the result. 
Result so far: 79264.29
The remainder is 323 after subtracting 7317 from 7640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 11:
813 goes into 3230 3 times with a remainder of 791.
Use 3 as the next digit of our solution. 
Result so far: 79264.293
Subtracting 2439 from 3230 leaves us with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Let's proceed to step 12:
The number 813 fits into 7910 9 times, leaving a remainder of 593.
Write down 9 as next digit of the result. 
Result so far: 79264.2939
If we subtract 7317 from 7910, we get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Moving on to step 13:
If we divide 5930 by 813, we get 7 and a remainder of 239.
Write down 7 as next digit of the result. 
Result so far: 79264.29397
If we take 5691 away from 5930, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 14:
The number 813 fits into 2390 2 times, leaving a remainder of 764.
Write down 2 as next digit of the result. 
Result so far: 79264.293972
Subtract 1626 from 2390 to get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 15:
813 can be fit into 7640 9 times, resulting in a remainder of 323.
Put 9 as the next digit of the answer. 
Result so far: 79264.2939729
Subtract 7317 from 7640 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 16:
If we divide 3230 by 813, we get 3 and a remainder of 791.
The next digit of our result is 3. 
Result so far: 79264.29397293
If we take 2439 away from 3230, we end up with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Our division results in 79264.29397293 with a remaining 7.91e-07.
